403禁止访问您没有访问存储文件夹的权限

Question

我有一个关于产品的项目。我已经运行“ php artisan storage：link”，并且创建了symlink。我可以将文件上传到存储设备，但不能下载。该项目在本地正常运行。当我在公用文件夹上运行“ ls -l”时，得到此输出

                drwxr-xr-x 2 root root    4096 Jul  3 19:05 css
            -rw-r--r-- 1 root root       0 Jul  3 19:05 favicon.ico
            drwxr-xr-x 4 root root    4096 Jul  3 19:05 images
            -rw-r--r-- 1 root root    1823 Jul  3 19:05 index.php
            drwxr-xr-x 2 root root    4096 Jul  3 19:05 js
            -rw-r--r-- 1 root root     133 Jul  6 14:49 mix-manifest.json
            -rw-r--r-- 1 root root      24 Jul  3 19:05 robots.txt
            drwxr-xr-x 3 root root    4096 Jul  3 19:05 scripts
            lrwxrwxrwx 1 root root      60 Jul  7 16:25 storage -> /var/www/vhosts/example.com/httpdocs/storage/app/public
            -rw-r--r-- 1 root root 7482034 Jul  3 19:05 storage.zip
            drwxr-xr-x 4 root root    4096 Jul  3 19:05 styles
            drwxr-xr-x 2 root root    4096 Jul  3 19:05 svg

我在根目录上的.htaccess是;

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews -Indexes
</IfModule>

RewriteEngine On

# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

</IfModule>

我正在使用的Centos 7 OS和plesk面板。有人可以帮我吗？
